| Partial Lack of N-Acetyl Substitution of Glucosamine in the Peptidoglycan of the Budding Phototrophic Rhodomicrobium vannielii  | | | Abstract
| The rigid layer and peptidoglycan fractions from two strains (A TC C 17100 and R m 5) o f the budding phototrophic Rhodomicrobium vannielii were isolated. Rigid layers of both strains con tain protein in addition to peptidoglycan. They were free o f polysaccharides and fatty acids. The respective peptidoglycan fractions contain glucosam ine, muramic acid, l -and D-alanine, D-glutamic and m eso-diam inopim elic acid in approximately equimolar ratios except for a signifi cant lower relative D-alanine content. A nalysis o f partial acid hydrolysates revealed A 1 '/-type structure of Rhodomicrobium vannielii peptidoglycan (shown with strain ATCC 17100). An about 10—30% lack o f N-acetylation o f glucosam ine was indicated. The degree o f cross-linkage was found to be about 60% . No differences in peptidoglycan com position and degree o f cross-linkage were found between swarmer-and chain-cells as exam ined with strain R m 5. | | |
